Abstract

The present invention measures an actual utilization frequency of data and controls a location of this data in a storage apparatus in a case where a host computer makes joint use of a storage apparatus and a cache apparatus. A portion of data used by an application program 1A is stored in a storage apparatus 2 and a cache apparatus 3. A management apparatus 4 detects an I/O load of a page (4A), and detects an I/O load of cache data (4B). The management apparatus 4 determines a corresponding relationship between the page and the cache data (4C), and adds the I/O load of the cache data to the I/O load of the page.
